error ID: 462831189 [MLZ] downloaded Zip file not found
The error above started appearing on my windows office pc. Sync between my laptop and home machine (both OSX) work fine. but my office pc is now out of the loop it seems. I have no clue what zip file is causing the problem. any help would be great.
Downloaded ZIP file not found in Zotero.Sync.Storage._processDownloadedZip()
If that's the error, the OS is just failing to create a temporary directory that it needs. According to Dan's response on a similar issue, the most common cause is a problem with the system's security settings.

If a check of the security settings and (just to be safe) a check of the available local disk space does not turn up obvious problems, we'll need to dig a little deeper.
So security software is quite likely at fault here.
